Full-scale testing is useful to achieve a better understanding of how pipelines respond to loading conditions that can lead to failure. A well-designed test program can validate numerical modeling efforts, thus improving the overall confidence in the analysis results. In addition, testing can provide engineers with insights on in-service behavior and threats to pipeline safety. Testing can also be a powerful tool to predict the future performance (establish reassessment intervals) of pipelines to meet integrity assessment requirements.
For more than a decade, Stress Engineering Services has been using full-scale testing methods to help pipeline companies assess the condition of their pipeline systems in support of their integrity management program. The engineers and technicians at Stress Engineering Services are leading experts in full-scale testing methods that aid in predicting the future performance of pipeline materials with anomalies such as dents, wrinkle bends, and flaws in seam welds and vintage girth welds.
Bending loads can be used to simulate pipeline conditions such as thermal buckling, land movement, and pipe/soil interaction. Simultaneous effects of internal pressure and axial tension or compression can also be applied.
